A new study has shown the true earning potential that free iOS apps have achieved. The study compared several different types of advertisement-supported apps on iOS and Android platforms and analyzed how much money they were able to make per user. The results show pretty clearly that ad-supported apps can easily rival the paid variety in terms of earning potential.

Neverending one-button platformers have become extremely popular on the iPhone over the past year. Games like Canabalt proved you didn't need complicated design to engage players for hours. Now, indie developer Honeyslug is taking that formula a step further with their new release Poto and Cabenga. You control not one, but two characters with a single button.

Tower defense games on the iPhone are extraordinarily common. Most of them fade into obscurity and are forgotten within days of their release. TowerMadness is one of the few and the proud that continues to stand above the rest and serve as a mark of quality. It's probably not as good or as popular as Fieldrunners, but this new update is definitely a step in the right direction.

There are literally hundreds upon hundreds of awesome classic games currently available on the iPhone. We should know; we just picked up 10-15 of them during yesterday's awesome mega sale.

Which is why Civilization V has been such an amazing experience for Mac gamers. Not only is it an amazing strategy game, but it also released on Mac fairly soon after the PC. Now the developer is releasing seven new downloadable content packs that bring the Mac version fully up to speed with the PC.

In what can safely be called a "cautionary tale," a young girl named Madison (currently attending second grade) racked up a gargantuan $1400 bill for her parents this week while playing Smurfs' Village - a Farmville-esque freemium online game. The item that caught her eye? Dozens of barrels of delicious, delicious smurfberries.

There's officially no good reason to pay more than 99 cents for any game on the App Store today. We always thought Valentine's Day was the kind of holiday that specialized more in cheap pink teddy bears than smartphone software, but apparently we were wrong. The past couple of weeks have been positively flooded with huge iOS video game sales from major publishers, and now Sega, Capcom, and Namco are getting in on the action. Some of their very best games are included so check out the full list.

John Carmack has created some of the greatest video games of all time. He's helmed successful companies, has more than twenty years of experience in the video game industry, pushed the boundaries of iOS gaming with the recent release of Rage. Oh, and he also moonlights as a rocket scientist as the lead engineer of his own aerospace company, Armadillo Aerospace. When this guy talks, people listen.

Apple lifers probably know the story of Marathon all too well at this point. The gaming series that made Mac gaming great in the mid-1990s could now possibly return on the iPad. However, the game's developer has reached a few roadblocks which are preventing the game's release as of now.
